Slurp doesn't receive simulate mouse pressing event

slurp 1.5.0-1
sway 1.10
I  simulate mouse pressing  to slurp via
```
slurp -p & sleep 1; swaymsg 'seat - cursor press button1';  swaymsg 'seat - cursor release button1'
```
OR
```
{ sleep 1; swaymsg 'seat - cursor press button1';  swaymsg 'seat - cursor release button1';  } & slurp -p
```
All seems slurp doesn't receive simulate mouse pressing event.
